Abstract: In order to navigate in interactive voice services (PSV) implemented on a platform and accessible from a user terminal (TU) and executed in a first language in an interactive voice server (SVI), e.g., VXML, the voice services include identifiers of other voice services or of portions thereof, which in turn include returns to the voice services. In the platform (PSV) the description of a voice service from an administrator terminal (TA) is written in a high-level language of the invention which is converted into the first language during the service call so as to be executed in the voice server. Thus, the invention networks voice services while facilitating publishing thereof.

Abstract: A control unit for processing modules of an integrated circuit for data processing includes at least one control module which is formed by a control operator and a gating means which exchanges input/output semaphores with upstream and downstream control modules and/or with processing modules. Each control operator, controlled by its gating means, receives microinstructions from an upstream control module and supplies microinstructions to one or more downstream control modules and/or microcommands to a downstream processing module. The control operator may comprise either a sequencer and a memory or a programmable logic array. The exchanges being controlled by the semaphores, each control module incorporates self-clocking sequencing. The control unit enables a modular design for the integrated circuit for data processing.
